Which SR Blue fuse for ARC REF 5SE? It says 5A slo/blo 250V on the fuse but no size MM?any help? Anyone had any experience with either fuse and what was the result.
I’ve been in the fancy fuse game ever since Isoclean, yes they’re UL rated, came on the scene nearly 20 years ago. So, I was one of the first. But I never had a fuse blow. I’ve also had Audio Magic Nano fuse. Never blew. Boy, was I lucky!
The only fuses I've used in recent years that blew were SR Black fuses I was testing for their sound. Also, I concluded that they had no impact on the sound of the components I stuck 'em in, and after testing I sent the pile of them back to my source. I'm sticking to Littelfuse and other stock fuses that work fine and, like any other well sorted fuse, have zero impact on the sound except when they melt.
So all that talk about other's poorly designed power supplies in their lousy amps and their boutique fuses was just a lot of hot air because you decided to build an amp that would often fail by design because you seem to think it sounds better that way?
You keep citing Nelson Pass's designs as the inspiration for yours and yet I've yet to hear of any fuses popping with regularity with his amps. If they did, we'd all hear about it by now and no one would be buying them.
Bartender, find out what he's drinking and order me a case! 😄
In my case the blown fuse was a little bit of user error as well as a little manufacturer error. I was listening pretty loud when I switched on the fly from the triode to UL, instantly doubling the watts. Later in discussing with the manufacturer, they recommended using a 4 amp fuse instead of the 3 amp fuse that came with the amp stating that you can usually get away with a 3 amp fuse but switching surges can sometimes pop the 3 amp. Since then I always reduce the volume when switching from triode to UL and have never had a problem since, even with a 3 amp fuse.
three_easy_payments, kosst_amojan, analogluvr, mrdecibel, and anyone who I might have missed,
Thanks for responses. I believed fuses may blow, they would not be putting them in otherwise, but was wondering how common that really is. I guess more common than I observed. Maybe mrdecibel and I are simply lucky.
If you’re foolish enough to waste good money on boutique fuses, add an additional real fuse in line with the boutique fuses so there’s some real protection. Boutique fuses aren’t UL or CSA approved or tested in any meaningful way.
PADIS fuses are UL, PSE and SEMKO approved and they are "boutique" fuses.
Hey... If you don't believe me about tuning fuses frying stuff, listen to a guy who's seen it.

" I have had plenty of fuses blow because my amp has a massive power supply ". Many amps being sold have massive power supplies, and if fuses were to continue to blow, I think these amps would be right back to the manufacturer for constant repair, or replacement. Enjoy ! MrD.
Yes, why can’t the "same " trolls let the fuse folks have their fun. Why must they show up, over and over and over again. This is a hobby. Enjoy ! MrD.
Here's a perfect example of why that other tread was shut down: the hyperbolic, over the top, harping fish wives are taking residence in yet another fuse thread to wreak their havoc. 😄
@glupson I recently had an AC fuse in my IEC connector blow when switching from triode to UL mode. Turn on and switching surges popping fuses is not as uncommon as you may think. In fact you can search the forum and find others here posting about it over the years.
Regardless of which fuse blows when and what manufacturer it was, how many of you have actually had any of the fuses blow? I have never had it happen, may be just a pure luck, or have never heard it happen to anyone I know.
There was a thread a few years ago regarding aftermarket fuses and the possible dangers of using them. The subject was not about whether or not there is an audible difference vs. stock. Many of our resident experts participated and the result was there were no reports of components being fried or catching fire if the proper value fuse was used.
Relax, Costco, reversing a fuse never blew anything up. Nobody’s house burned down. Give me a break! You guys are behaving just like Chicken Little. 🐥 The sky is falling! The sky is falling!
Yes the SR fuses blow as designed! If anything compared to stock fuses they may blow more readily 😀 talk to your supplier about rating or replacement if you have issues with power on surges
Just so I understand, these SR fuses work as protective fuses, correct? A SR 4 amp fuse should blow when that current is exceeded correct? I mean otherwise it's not a designed fuse and it's just a piece of metal. I'm not so concerned about the UL listing, I just want to make sure they blow when they are supposed to and that there is a performance spec associated with their design. I ordered a SR blue last week and now you guys have me worried about even using it.
Before Geoffy The Fuse Troll jumps in, remember that SR fuses are not UL or CSA approved. You still need a legitimate fuse to meet electrical safety bureau driven requirements. Otherwise, if there’s an electrical fire due to the equipment with the boutique fuse, your insurance claim will be denied.
Better be safe than sorry. Spend the extra several hundred dollars on music.
you need the large fuse, as there can often be a turn on surge with this pre it is worth going up a size and using the 6.3A. That’s what I used in my Ref 40. The black is good but the Blue is better and benefits from less need for burn in
